To all whom it m/my concern:

Be it known' 'that I, HENERY SCHNEIDER, residing at Kenton, in the county of Hardin and State of Ohio, have invented certain new and useful Improvements in GaseousFuel Burners, of which the following is a specification.

My invention relates to improvements in that type of gaseous-fuel burners more es ecially designed for use in the ordinary ma es of cook-stoves and ranges; and it primarily has for its object to provide a burner of the character stated of a simple and economical construction which can be easily a plied to ordinary cook-stoves or ranges without disorganizing the construction thereof and which can be readily adjusted to suitthe desired el consumption and heating qualities.

In its eneric nature my inventioncomprehends a urner comprising a body portion of tubular or pipe-like shape having a plurality of cored-out mixing-chambers arranged to form a main com artment which is used when a maximum eat for the burner is required and a. supplemental compartment cooperatively arranged with the main compartmentwhereby to, form, as it were, under one adjustment of the valve pipes that constitute a part of my complete burner a continuation or part of the main burner and under another ad ustment of the valve devices to form an independent or jet burner for keeping up a" minimum flame.

In its more subordinate features my invention consists in certain details of construction and peculiar, combination of parts, all of which will be first described in detail and then be specifically pointed out in the ap-- is a detail section on the line 4 4 of Fig. 3,

illustrating the adjustment of the valve for feeding into the main combustion compartment of the burner and closing off the supplemental compartment. view showing the valve shifted to close ofl the main compartment andopen up the feed to the supplemental compartment. Fig. 6 is a transverse section on the line 6 6 of Fig. 3.

Fig. 5 is a similar,

Fig. 7 is -a detail view illustrating a modified manner of connecting the mixer-cap and the feed-pipe.

In the practical construction my invention comprises a tubular body A, having two compartments or cored-out sections, one of which, a, is about one-half the diameter of the body A and extends about halfits length, while the other, 0/, extends approximately the full length of the body A and at the front end surrounds the casing of the other chamber a, which atthe inner end is closed off from the chamber a by a solid head a.

At the outer end the body A has an integral extension, which is cored out at ri ht angles to the longitudinal cores a ato orm a valve-chamber a, which has an inlet 3, that communicates with the extension a, having an external thread 4 to receive a detachable mixer-cap B, which has a threaded boss b to engage the extension a, a series of air-inlets 4 and an extension a threaded to receive the threaded end f of the gas-feed pipe F, as clearly shown in Fig. 3. p

In Fig. 7 is shown a slightly-modified arrangement of the mixer end of the burner. In this latter form the extension has the mixer-head integrally formed therewith and the said head has its extension a provided with a set-screw 5 to clamp against the feedpig? as shown in Fig. 6 aforesaid.

I ithinthe valve-chamber is mounted a taperin valve 0; the lower end of which is detacha ly connected with the lower end of the valve-casing, while its upper end has an annular flange c, that rides on the top edge :1: of the valve-casing, which flange at one;

side has a segmental cut-out portion a, the opposite edges 2 of which are arranged to a ternately move into engagement with a stop-lu a on the valve-casing for a purpose resent y ex lained, and the top of the valve as a suitab e thumb and finger piece a, as shown.

The body of the valve 0 has a transverse bore 0 of a diameter sufliciently large to be in direct communication with the inlets 1 and 2 of the main and supplemental combustionchambers a 0/ when the said valve Cis adj usted to its'central position, as shown in Fig. 2, and the front portion of the bore 0 1s widened laterally, as at 3 3, whereby to maintain an open communication with the inletport 3 in the valve-casing during all of the adjustments of the valve 0.

The shape of the valve-bore c and the corinto position, as indicated by the arrow 20,

- ment orburner a in'the manner shown and body, and by reason of the supplementalv constr'uctionshown in .Fig. 7 is employed.

relative arrangement therewith of the sev- Y eral ports or openings 1, 2, and 3 in the valvecasing is such that by turning the valve in the direction indicated by the arrow 10 in Fig. 4 until the edge e engages the stop-lug a, which limits the adjustment of the valve 0 in the direction indicated, the 0 enin 2 to the supplemental chamber a wil be c osed, while the ports 1 and 3 remain open to lead the mixed air and gas into the main compartments 0 only, and when the valve C-is shifted the feed-opening 1 to the main compartment will be closed off and the air and gas will be now fed to the supplemental com artment or burner a only, it being understoo that under either adjustment of the valve 0, as stated, the said valve need not be turned to the limit of its movement, but can beheld partly 0 en toregulate the amount of fuel-supply to sit er compartment (1 a, as may be desired.

By arranging the supplemental and main combustion or burner compartments a a in the manner stated it will be noticed that the jet or burner openin s for the main burner aracontinued the ful length "of the tubular burner a being almost entirely within the main burner the up er or crown portion thereof is formed by t e continuation of the upper or crown portion of the main burner.

M construction of burner, it willbe notice can be readily fitted within the firebox of an ordinary cook-stove or range by simply -formi an aperture 00 in the front end of the',saiifire-box sufliciently lar e for the passage of the burnersbody A, whic can be readily made fast-to the feed-pipe by threading onto the pipe or clamping the same by the clamping-nut when the modified By arranging the supplementalcompart-- described a great saving of fuel is effected,

since when using but one of the stove-holes, as shown in Fig. 1,0nly that part of the burner directly under the said hole is used and the' flames directed against the pot or utensil over the one hole. I

Having thus described my invention, what 5o I claim, and desire to'secure'by Letters 'Pat-.

cut, is

' 1. An improved gaseous-fuel burner consisting of a body portion having two longitudinal independent chambers, one of which is of less length and area than the other, each having burner-holes that discharge through the bod a valve-casing that forms a part of the b0 y, said casing having discharges at one side in line with the entrant end of the two chambers, and an inlet at the other side in communication with the feed-pipe, a stop on said casing and a valve rotatably mounted in the casing having a single cross-port. ar-

ranged to continuously communicate with the feed-inlet and to alternately cut out either of the chambers-or to lead into both chambers at the same time, said valveh-aving stop portions adapted to engage thestop on the casing for the purposes described.

2. The hereinbefore-described improved aseous-fuel burner, which consists of a tubular body, closed at its outer end having burneropenings in its top andhavin'g-a short supplemental chamber at itsfQIWar-d end lemental chambers inthe body, and anin- 0 et-port at the opposite side,'.th e-said opposite side having a tubular extension, an airmixer secured tosuch extension having means for detachably supporting the discharge end of the feed pipe and a valve Withm the casing having a single cross-port arranged whereby under one ad'ustment of the valve, both chambers inthe body will be in open communication with the feed port,

under anotherv ad'ustment one of said cham- 9o berswill be close off and under another adjustment of said valve, the othercha her will be closed off for the purposes speci ed.
